The image was created using all three of NASA's major observatories — the Chandra X-ray Observatory and the Hubble and Spitzer space telescopes. The green-colored wisps recorded by Hubble, represent the light that is emitted from stars undergoing different stages of development. Gases that have been heated to millions of degrees by supernova explosions and stellar winds, seen in blue, were detected through X-rays observed by Chandra. Finally, the red clouds of gas and dust were captured using infrared emission data from Spitzer.
